Colorado Supreme Court Concludes (Unsurprisingly) That Elephants Aren’t Persons

On January 21, 2025, the Supreme Court of Colorado affirmed a lower court ruling that elephants maintained in a zoo were not properly the subject of a habeas corpus petition pursued by the animal rights group, Nonhuman Rights Project (NRP). Nonhuman Rights Project, Inc. v. Cheyenne Mountain Zoological Society, No. 24SA21 (Colo. Jan. 21, 2025). As the court observed, “We are not alone in rejecting NRP’s attempt to extend the great writ to nonhuman animals. . . . Every one of [NRP’s] petitions for writ of habeas corpus has been denied for the same or very similar reasons.” Slip op. at 16.

NRP filed the writ arguing that five elderly African elephants (Loxodonta africana) located at the Cheyenne Mountain Zoo (Missy, Kimba, Lucky, LouLou and Jambo) were “unlawfully confined” and should be relocated to an elephant sanctuary. Petitioner argued that elephants held in a zoo are prone to suffer from “chronic frustration, boredom, and stress, resulting over time in physical disabilities, psychological disorders, and, often, brain damage.” Slip. op. at 6. The zoo “vigorously disputed the factual allegations in the Petition, pushing back against the suggestion that the elephants were receiving anything short of remarkable care.” Id.

The Supreme Court concluded that habeas relief was unavailable here because the Colorado habeas statute only applies to “persons,” and “persons” means human beings:

Colorado’s habeas corpus statute does not define the term “person.” It is, however, defined by section 2-4-401, C.R.S. (2024), which contains definitions that “apply to every statute, unless the context otherwise requires.” Under section 2-4-401(8), “‘Person’ means any individual, corporation, government or governmental subdivision or agency, business trust, estate, trust, limited liability company, partnership, association, or other legal entity.” Looking to the dictionary, the term “person” is defined as an individual human being. See Person, Black’s Law Dictionary (12th ed. 2024) (“[a] human being”); Person, Merriam-Webster Dictionary, https://www.merriam-webster.com/dictionary/person [https://perma.cc/6AX5-9MCH] (“human, individual”).


Given the statutory definition of the term “person” and the plain and ordinary meaning of the term found in the dictionary, we conclude that the General Assembly’s choice of the word “person” demonstrates its intent to limit the reach of section 13-45-102 to human beings. Our conclusion is further bolstered by the fact that including nonhuman animals in the definition of the term “person” is the type of monumental change in the law that one would reasonably expect the General Assembly to make explicit. That is, “[i]f [the General
Assembly] intended to take the extraordinary step of authorizing animals as well as people . . . to sue, they could, and should, have said so plainly.” [Slip op. at 14-15 (citation omitted).]

The court likewise was not persuaded that the common law writ of habeas corpus was available: “[N]othing in the common law supports NRP’s position, which rests primarily on a concurring opinion and two dissenting opinions in its unsuccessful efforts to extend the writ of habeas corpus to nonhuman animals.” Slip op. at 16. This was the case notwithstanding NRP’s argument that elephants are “autonomous:” “Habeas protections flow from the status of being a person, not from a being’s ability to pass some type of autonomous capacity test.” Id. at 18.

It also was significant that NRP was not seeking to actually “liberate” the elephants but, instead, to move them to another form of confinement in a sanctuary: “The fact that NRP merely seeks the transfer of the elephants from one form of confinement to another is yet another reason that habeas relief is not appropriate here.” Slip op. at 19.

As the court summed it up:

Simply put, no Colorado court, nor any other court in any other jurisdiction in the United States has ever recognized the legal “personhood” of any nonhuman species. [Slip op. at 17.]

NRP has, for years, sought to push its animal rights agenda by burdening zoos and other exhibitors with habeas petitions seeking to move elephants to sanctuaries on the theory that holding such an animal in a zoological setting is deleterious to the animal’s welfare. (We have written about NRP’s actions several times, for example here.) Such assertions of poor welfare generally are baseless. For example, litigation involving the Ringling Bros. Circus elephants demonstrated that they generally lived longer than their wild counterparts. In fact, Ringling had one circus elephant who lived well into her mid-70’s. One would think that these habeas petitions would, at some point, be found by the courts to be frivolous.

Nonhuman Rights Project Loses Another Habeas Case for Elephants

As we have reported previously (here, here, here, here), an animal rights group called the Nonhuman Rights Project (NhRP) has a history of filing fruitless cases to establish that animals should have the same basic rights as people.  NhRP has used the common law and statutory writ of habeas corpus in an effort to “liberate” elephants and apes from various U.S. zoos and other facilities.  None of these cases has succeeded.  The most recent failure occurred this month in Colorado where a state court judge denied a habeas writ with respect to five African elephants residing at the Cheyenne Mountain Zoological Society.  Nonhuman Rights Project, Inc. v. Cheyenne Mountain Zoological Society, et al., No. 23CV31236 (Colo. Dist Ct., El Paso County Dec. 3, 2023). Continue reading “Nonhuman Rights Project Loses Another Habeas Case for Elephants”

On February 18, 2020, a trial court in Bronx County, New York, denied a habeas corpus petition filed by the Nonhuman Rights Project (NhRP) on behalf of “Happy,” a 48-year old Asian elephant residing in the Bronx Zoo.  Nonhuman Rights Project v.

Update on Elephant Habeas Corpus Case

by John M. Simpson.

We recently reported on a case in which an animal rights group, the Nonhuman Rights Project,  sought habeas corpus relief for three Asian elephants maintained in a zoo in Connecticut.  The Connecticut Appellate Court affirmed the lower court’s judgment and ruled that the plaintiff had no standing  because the elephants themselves had no standing.

Connecticut Appellate Court Denies Habeas Relief for Elephants

by John M.  Simpson.

On August 20, 2019, a panel of the State of Connecticut Judicial Branch Appellate Court officially released a decision affirming the dismissal of an action that had been brought seeking habeas corpus relief for three elephants maintained at a zoo in Goshen, Connecticut.  Nonhuman Rights Project, Inc. v. R. W. Commerford and Sons, Inc., No. AC 41464 (Conn. App.  Aug. 20, 2019).  The petitioner Nonhuman Rights Project sought to represent the elephants as their “next friend” seeking to vindicate what was described as the animals’ “common-law right to bodily liberty.”  The lower court dismissed the case on the grounds that petitioner lacked standing and, alternatively, that the petition was “wholly frivolous.”  Continue reading “Connecticut Appellate Court Denies Habeas Relief for Elephants”

Court Denies Habeas Petition Filed on Behalf of Elephants

By John M. Simpson

A Connecticut Superior Court Judge recently issued an opinion further elaborating on his prior decision to deny a petition for a writ of habeas corpus filed on behalf of three elephants (two Asian and one African) owned by a zoo in Connecticut.  Nonhuman Rights Project, Inc. ex rel. Beulah, Minnie and Karen v. R.W. Commerford & Sons, Inc., No. LLICV175009822S, 2018 WL 3014069 (Conn. Super Ct. May 23, 2018).  The action had been brought on behalf of the elephants “Beulah,” “Minnie” and “Karen” by the Nonhuman Rights Project (NHRP), arguing that the animals possessed emotional, social and intellectual attributes sufficient for common law personhood and for the common law right to the bodily liberty protected by the writ.  The May 23 decision expanded upon the reasons why the court previously had found the habeas petition to be “wholly frivolous on its face.” Continue reading “Court Denies Habeas Petition Filed on Behalf of Elephants”
